54-72 cm length | 78-97 cm wingspan | 900-2160 gm weight
A large duck with a long, rather thin and serrated bill.
The drake has a white body with a black back, grey rump and an iridescent, black-green head. The white plumage may have a salmon-pink tinge to it, from the carotenoids in their diet. The hen is grey, darker on the back and wings and lighter underneath, has a white chin and a rusty head. Males in eclipse plumage look similar to the female. Both sexes have bright, orange-red legs, feet and bill. Juveniles look like the adult female, but with a stripe between the eye and the bill and with duller legs and bill.
